The technical solution of the present disclosure has the following advantages.
1. Cooling Operation Mode of the Thermostatic Garment:
A positive pole of the power supply is connected to the N-type semiconductor of the thermoelectric cooler, and a negative pole of the power supply is connected to the P-type semiconductor of the thermoelectric cooler. The thermoelectric cooler absorbs heat on one side of the first heat conducting tank connected to the thermostatic garment inner layer, thereby lowering the temperature of the water in the first heat conducting water tank. The cold water in the first heat conducting water tank is driven by the first water pump connected to the thermostatic garment inner layer to circulate and flow in the first heat exchange water pipe network of the thermostatic garment inner layer through the first connecting water pipe, thereby taking away the body heat. At the same time, the thermoelectric cooler is heated on one side of the second heat conducting water tank connected to the thermostatic garment outer layer, thereby raising the temperature of the second heat conducting water tank. The hot water in the second heat conducting water tank is driven by the second water pump connected to the thermostatic garment outer layer to circulate and flow in the second heat exchange water pipe network of the thermostatic garment outer layer and the heat dissipation effect is achieved by contact with the outside air. The present technical solution has the advantages of good heat dissipation. The temperature of the water in the first heat conducting water tank is monitored by the first temperature sensor used by the controller, and the power supply of the thermoelectric cooler is controlled (e.g. controlling the current direction and magnitude of the cooling sheet) to obtain a constant temperature according to the water temperature.
2. Heating Operation Mode of the Thermostatic Garment:
The direction of the power supply of the thermoelectric cooler is switched. The positive pole of the power supply is connected to the P-type semiconductor of the thermoelectric cooler, and the negative pole of the power supply is connected to the N-type semiconductor of the thermoelectric cooler. The thermoelectric cooler is heated on one side connected to the first heat conducting water tank, thereby raising the temperature of the water in the first heat conducting water tank. The hot water in the first heat conducting water tank is driven by the first water pump connected to the thermostatic garment inner layer to circulate and flow in the first heat exchange water pipe network of the thermostatic garment inner layer through the first connecting water pipe, thereby providing heat to the body. At the same time, the thermoelectric cooler is providing cooling on one side of the second heat conducting water tank, thereby lowering the temperature of the second heat conducting water tank. The cold water in the second heat conducting water tank is driven by the second water pump into the second heat exchange water pipe network on the thermostatic garment outer layer to circulate and flow, and the heat exchange is achieved by contacting outside air. The temperature of the water in the first heat conducting water tank is monitored by the first temperature sensor used by the controller, and the power supply of the thermoelectric cooler is controlled (e.g. controlling the current direction and magnitude of the thermoelectric cooler) to obtain a constant temperature according to the water temperature.
Another heating operation mode of the thermostatic garment body:
The electric heating sheet is heated by the power supply, thereby raising the temperature of the water in the first heat conducting water tank. The hot water in the first heat conducting water tank is driven by the first water pump to circulate and flow in the first heat exchange water pipe network of the thermostatic garment inner layer through the first connecting water pipe, thereby providing heat to the body. The temperature of the water in the first heat conducting water tank is monitored by the first temperature sensor used by the controller, and the power supply of the electric heating sheet is controlled to obtain a constant temperature according to the water temperature.
In summary, the thermostatic garment of the present disclosure adopts a thermoelectric cooler for cooling and heating and can be heated by an electric heating sheet as well. The cooled or heated water is driven by the first water pump to circulate in the first heat exchange water pipe network arranged on the thermostatic garment inner layer in a laying manner, thereby achieving the function of cooling or heating the body. Due to the use of electric heating or cooling, it is not necessary to pre-install a large amount of water in the first heat conducting water tank, thereby reducing the volume and the weight of the water tank which makes the thermostatic garment convenient to carry. The adopted thermoelectric cooler and the electric heating sheet have the advantages of small volume, light weight, no moving parts, high efficiency, stable and reliable operation, and further makes the thermostatic garment convenient to carry. In addition, when the thermoelectric cooler is heated on one side of the second heat conducting tank, the temperature of the second heat conducting tank increases. The hot water in the second heat conducting water tank is driven by the second water pump to circulate and flow in the second heat exchange water pipe network, and the heat is dissipated by contact with the outside air. The present technical solution adopts water circulation for heat dissipation in the heat exchange water pipe network and has the advantages of good heat dissipation owing to the large contact area with the ambient air and does not require the use of a fan for cooling, thereby reducing noise and improving reliability.

In this arrangement, the water tank can be arranged at different angles and directions without influencing the conveying of the water to the heat exchange area, and the water in the water collecting area 1413 only needs to cover the water outlet side hole 1441 of the water outlet pipe 144 to prevent air from entering the water outlet pipe 144. That is preventing the air from being sucked into the water pump and thereby keeping the water pump running normally.
In one embodiment, the thermoelectric cooler 6 includes an array structure formed by the plurality of P-type semiconductors 62 and the plurality of N-type semiconductors connected 61 in series, wherein the P-type semiconductors 62 and the N-type semiconductors 61 are spaced apart.

the upper heat conducting layer 63 and the lower heat conducting layer 64 are arranged opposite to each other. A material of the upper heat conducting layer 63 and the lower heat conducting layer 64 may be both alumina ceramic. The alumina ceramic has good heat conduction, good heat dissipation effect, a high heat conducting coefficient, good stability, and safety due to the insulation. The upper heat conducting layer 63 and the lower heat conducting layer 64 are respectively additionally arranged on an upper end and a lower end of the array structure. The upper heat conducting layer 63 is fixedly connected with at least one conductive metal sheet 65. The lower heat conducting layer 64 is fixedly connected with at least two conductive metal sheets 65, and the number of the conductive metal sheets 65 fixedly connected to the lower heat conducting layer 64 is one more than the number of the conductive metal sheets 65 fixedly connected to the upper heat conducting layer 63. The N-type semiconductor 61 and the P-type semiconductor 62 are fixed on each of the conductive metal sheets 65 on the upper heat conducting layer 63. Other ends of the N-type semiconductor 61 element and the P-type semiconductor 62 element fixed on the same conductive metal sheet 65 on the upper heat conducting layer 63 are respectively fixed on two adjacent conductive metal sheets 65 on the lower heat conducting layer 64. The conductive metal sheets 65 on the left and right ends of the lower heat conducting layer 64 are connected to the positive and negative poles of the direct current power supply 9. Ends of the upper heat conducting layer 63 and the lower heat conducting layer 64, away from the array structure, are respectively connected to the first heat conducting water tank 11-1 and the second heat conducting water tank 11-2.
The working principle and the beneficial effect of the above technical solution are as follows. The above structure is simple and is convenient to control the cooling sheet to perform cooling or heating by changing the current flow direction.
In one embodiment, a closed accommodating space is formed between the upper heat conducting layer and the lower heat conducting layer. The corresponding edges of the upper heat conducting layer and the lower heat conducting layer are bonded. The array structure is located in the accommodating space and in the array structure. The plurality of P-type semiconductors 62 and the plurality of N-type semiconductors 61 are collinearly arranged along an arrangement direction of the array. The P-type semiconductors 62 and the N-type semiconductors 61 are spaced apart in the accommodating space. A first gap is arranged between the adjacent P-type semiconductors 62 and the N-type semiconductors 61. A second gap is formed between the adjacent P-type semiconductors 62. A third gap is formed between the adjacent N-type semiconductors 61. An inert gas is filled in the first gap, the second gap and the third gap. The inert gas (for example, argon) refers to a group 18 element on the periodic table.
The working principle and the beneficial effect of the above technical solution are as follows. An inert gas is filled in the accommodating space between the upper heat conducting layer 63 and the lower heat conducting layer 64 in the above technical solution. The heat conducting layer 63 and the lower heat conducting respectively perform cooling and heating. The above technology can be used to cut off the heat exchange between the upper heat conducting layer 63 and the lower heat conducting layer 64, so as to improve the cooling efficiency of the cooling layer and the heating efficiency of the heating layer, leading to good cooling and heating effects.

a liquid crystal display panel;
an up selection button, a down selection button and a confirmation button. The up selection button, the down selection button and the confirmation button are all hard buttons.
a microprocessor, liquid crystal display panel, the up selection button, the down selection button, the confirmation button and the controller are all connected to the microprocessor; and
the microprocessor selects the functions of heating, cooling, water pumping and fanning and sets a target temperature in the menu by the up selection button, down selection button and confirmation button. The microprocessor displays information of menu options, set temperature, actual temperature and current operating status via the liquid crystal display panel.

Users select the functions of heating, cooling, water pumping and fanning and sets a target temperature in the menu through the up selection button, the down selection button and the confirmation button. A control signal corresponding to a button is input to the microprocessor after being selected. For example, after the cooling option in the menu is triggered and the target temperature is set by the button, the microprocessor outputs a control signal for controlling the thermoelectric cooler 6 to the controller by comparing the actual temperature detected by the first temperature sensor 160 with the set target temperature, and simultaneously outputs a first water pump 10-1 control signal and a second water pump 10-2 control signal to the controller. The thermoelectric cooler 6, the first water pump 10-1 and the second water pump 10-2 are controlled to operate by the controller. After the heating option in the menu is triggered and the target temperature is set by the button, the microprocessor outputs a control signal for controlling the thermoelectric cooler 6 or controlling the electric heating sheet 7 by comparing the actual temperature detected by the first temperature sensor 160 with the set target temperature, and simultaneously outputs a first water pump 10-1 control signal to the controller. The thermoelectric cooler 6 or the electric heating sheet 7 and the first water pump 10-1 are controlled to operate by the controller.
